FLOOD-GATE.

Specification of Application filed June 11,

To all whom it may concern:

Be it known that I, Jnssn A. Benson, a citizen of the United States,'residing at Ada, in the county of Pontotoc and State of Oklahoma, have invented new and useful 1mproveinents in Flood-Grates, of which the following is a specification.

The object of the invention. is to provide a simple and inexpensive flood gate designed for farm and other rural use and adapted as in the ordinary practice to serve as a barrier to prevent stock from following the beds of streams and thereby wandering from one farm or pasture to another or from a farm to the road or vice versa, the construction of the gate being such that it may readily be adapted to streams of different widths and normal depths, regardless of the height of the banks, and having means whereby in the case of flood logs and other floating objects may readily pass thereover without riskorinjury to the levice.

Further objects and advantages will appear hereinafter, it being understood that the form, proportion and details of the construction illustrated may be resorted to within the scope of the appended claim without departing 'rom the spirit of the invention.

In the drawing Figure 1 is a general perspectiveview of a two-section gate embodying the essential features of the invention.

Fig. 2 is a transverse section al view of the same showing in dotted lines the depressed. position of the gate.

Fig. 3 is a detail longitudinal sectional view to show one of the intermediate hinge or pivot points with the related actuating or return spring.

Essentially the gate embodying the invention includes a sill 10 which is adapted to be arranged in the bed of the stream or run which is to be guarded, the same being suitably and permanently anchored as by means of posts or stakes 11 which, obviously, should be driven into the earthsufflciently foundation, and one or more gate members 12 suitably pivoted or hinged to bearing blocks 13 which ma be attached to the sill under such conditions as to range the pivots 1d substantially on the level of the bed of the stream.

Obviously any suitable material may be employed in the construction of the gate Letters Patent.

timber or metal, but for convenience the material indicated in the drawing is sheet metal, of proper gage to a. ford the requisite strength against transverse distortion, and to this end the same embodies a body plate 15, attached to or formed integral with an angle bar 16 with which are connected the aforesaid pivot members by which the mounting of the gate members upon the sill is efiected, upright slats or fingers 17 being secured as by bolts 18 to said body plate and preferably being of cross sectionally angular form, as shown, with their upper ends tapered or reduced to minimize friction of floating objects therewith and facilitate the passage of such objects without injury to the elements 0 the gate.

For convenience in multiplying the number of gate members to adapt the structure to be suited to streams of different widths, the intermediate pivot members are preferably telescoped so that the adjacent ter minal or marginal 'staves or uprig ts of adjacent gate members may be spaced at an interval corresponding substantially with those between thestaves or upright elements of each member, and thus present a more or the stream bed. that the gate members may be capable of yielding, and yet be automatically returnable to their normal or upright positions after having been depressed by the contact therewith of a floating object, or upon the subsidence of the flood by which they may have been effected, springs 18 are located adjacent to the pivot members and in such relation to the bearing blocks 13 to exert a constant yielding tendency to maintain the gate members in "said upright positions, stops 19 being located in thepaths of movement of suitable elements 0 the gate members, such as the horizontal flanges of the angle bars, to check' the return move- ..ient of the gate members when they have reached the upright position where. obviously, they are maintained by the effect of said springs.

From the foregoing description, it will be noted that a device of the structure submitted may be adapted to the bed of a stream of any ordinary width merely by the duplication or multiplication of sections or members, each of which may be of a convenient length to facilitate construction and transportation and each of which is adapted to sections, such as Also, in order exposed to the be depressed independently of the others, When encountered by a floating object of sufficient Weight, with tions of the 0th should one or more of the members be located in the ch annel of a stream and thus the incident contact of floating objects, Whil e others are located nearthe ba lower portions of the stream, narily stock could pass Without being exposed to the power of the current, the last named gate members would retain their position as barriers and thus serve their designed purpose of preventing the passage of the stock.

What is claimed is r 00d gate having in combination an anchor sill, spaced bearing blocks mounted out affecting the func- 1 er members, and therefore upon the anchor sill, plurality of gate members each provided low pivot studs of the gates and having one end bearing against the. block andfthe other and bearing against the stud it surrounds, so that the held normally but yieldably in tion. 7 V
